Application filed `IVlIay 2, 1921. Serialv No. 465,074. y

To all fio/tom t may concern.'

Be it known that I, WILLIAM C. LANG, a citizen of the United States,residing at Superior, in the county of Douglas and Sta-te of Visconsin,have invented certain new and useful Improvements in Grain Doors, ofwhich the following is a specification, ,reference being had therein tothe accompanying drawing. i

rlhis invention relates to certain improvements in car doors and has`special reference to what is commonly called a grain door for railroadcars.

The principal object ofthe invention is to provide a door havingimprovements over what is at present known in the art.

Other objects and advantages of the peculiar construction will appear inthe further description of the invention.

ln the accompanying drawing forming part of this application and inwhich like reference characters indicate like parts:

Figure l is a transverse sectional View through the car door openingfitted with one of the improvedattachments and the grain door partly inplace, the covering plate of the door post being removed;

Figure 2 is an outside elevation of the car having my improved doorattached thereto:

.Figure vis a vertical sectional view of the uppermost end of a doorpost illustrating the arrangement of sheaves over which the operatingline is reeved:

Figure 4 is a horizontal sectional view through one of the car doorposts in which the door engaging operating line reciprocates, and

Figure 5 is a plan view of the operatinghand wheel and its cooperativeparts.

l represents the usual door opening in the side of the ear Upon eitherside of the door opening is installed a vertically disposed,Arectangularly shaped, door post 3. The door post 3 'has formedthereintwo vertical rectangular slots, or cut away portions, the entirelength thereof, in either corner adjacent the door opening, as at f d,and which slots may be reinforced by suitable channel irons 5-5 and themetal covering plate 6. I l

Approximately one-third of the distance down from the upper edge of thedoor and adjacent each side thereof is pivotally attached a suspendingchain :24, there being eyefbolts 25l fined to the such attachment.

Members 26, having' eyes therein, are fastened to the under side of theroof of the car from which the chains @ai pivotally depend.' The doorbeing thuspivotally suspended aidjacent its uppermost edge will, whenraised by the operating line 27, assume a horizon'd tal elevatedposition-adjacent the ceiling vof the car as illustrated'in dotted linesin liig-` urel. v f

A short length of pipe 7 is installed in each door post adjacent theuppermost end thereof, the pipe being the 'same length as the width ofthe door post and pivotally supporting the small'A sheaves 8 8 and thelarger sheave 9. Slotted openings are formed in the bottom of the pipeso that the operating line may freely pass therethrough. n

Each operating line is securely fastened door to provide for passesthrough a suitable hole adjacent the bottom `of the door into theinnermost channel 4, up through the slotted openings'and over thesheaves in the pipe 7 and down the other channel l through suitableopenings in the floor of the car and isfastened to the operating drum.l2 `fined to the shaft 13 which is rotatably supported beneath the f asat l() to the bottom of the door l1, and

bottom ofthe car by the brackets le and l5.`

The bracket l5 is channelshaped in plan View and supports one end of theshaft 13, ,l

having the beveled gear 16 secured thereto, and the short stub shaft 17,to which is securely fixed the beveled gear 18 `which meshes with thegear 16. An operating wheel'l9 is fixed to the outer endof the shaft 17and by the rotation of which the door may be readily raised or lowered.

l have shown a wedgeshaped member 20, having a shoulder 21 formedthereon, as attached to the uppermost end of the door post and which isfor the purposev of mov# ing the door horizontally, when being raised toits uppermost position, away from the door-post 3 sufficiently so thatvthe upper kend of the door will rest in 'the bracket22 rigidly fixed inany desired manner to the f free end of which is lient outwardly anddownwardly in spiral iiorm for engagement with the 'aee 'the door as itis raised to adjacent its ultimato uppermost position and by whichengagement the free end of' the spring part a door.

Constant downward pressure upon the m ilus is ioi' the purpose ofafiording assistance when it is desired to close the door as when thehand wheei 19 is slacltened laway for the purpose oil allowing the doorto drop into position the pressure exerted by the springs 23 will impartinitial downward motion to the lower edge the door and thus assist inautomatic-ally closing saine.

Hai/ing thus described my invention what l claim and desire to secure byLetters Paten* is:

A pivotally suspended door oia the Charactor described for railway carshaving a horizontally disposed sha't for operating` saine externally ofthe ear, lines one end of is iiorced upwardly causing` it 'to ii-neaehoi which is wound about the shaft and y the opposite. end attached tothe door, door posts; each oi' said lines operating in spaced clntnnelsyin the corners oiI their respective door posts.

2. 'lhe combination with a grain door for cars which is closable againstthe posts of the door opening and slidable vertically against saidposts, oi: slots iorined in the two opposite corners oi? eaoh of theposts facing the opening, sheaves mounted at the upper endsv oi theposts, flexible means operative within the slots over the sheaves andattached to the door7 and manually operated shaft loeneath the doorexternally oi the oar for operating 'the flexible means. l

"En testimony whereof l hereunto ai'iix my signature in the presence oftwo witnesses.
